With the continuous development of the aerospace industry, the demand for high-performance, lightweight, high-temperature and corrosion-resistant materials has become more urgent. As a key material to meet this demand, titanium alloys occupy a pivotal position in the aerospace field due to their excellent mechanical properties and corrosion resistance. With the continuous advancement of titanium alloy machining technology, we have ushered in technological innovation in this field, opening up new possibilities for the manufacture and design of aerospace parts.

Importance of titanium alloys in aerospace

Titanium alloys have become the preferred material for key components in the aerospace field due to their high strength, low density, high temperature resistance, corrosion resistance and other excellent properties. Compared with traditional metal materials, titanium alloys have higher specific strength (unit mass strength), which can significantly reduce the weight of aircraft, improve fuel efficiency, and ensure the stability and safety of aircraft in high temperature environments.

Common aerospace titanium alloy applications include:

· Aircraft engines: turbine blades, compressor blades, combustion chambers and other components in high temperature and high pressure environments

· Fuse structure: such as wing frames, landing gear, door supports, etc.

· Spacecraft and satellites: such as propulsion systems and structural brackets, etc.

The use of titanium alloy materials not only provides excellent structural strength and durability, but also significantly improves the overall performance and safety of aircraft.

Challenges of titanium alloy machining technology

Titanium alloy has very strong hardness and toughness, which makes it face a series of challenges during machining:

· Fast tool wear: The high strength and hardness of titanium alloy easily cause the cutting tool to wear too quickly, increasing the difficulty and cost of machining.

· Large thermal deformation: Titanium alloy has poor thermal conductivity, and it is easy to generate a lot of heat during machining, causing workpiece deformation or tool overheating.

· Large cutting force: Titanium alloy materials have large cutting forces, which are prone to vibration and noise, affecting machining accuracy and surface quality.

· Corrosion problems: Although titanium alloy has excellent corrosion resistance, improper use of cutting fluid or improper operation during machining may cause surface damage.

Therefore, it is crucial to develop advanced technologies suitable for titanium alloy machining.
